JN0-647 Online Practice Questions and Answers

Your campus EX9200 core devices are highly oversubscribed on bandwidth and reporting massive dropped packets. To immediately address the issue, you decide to implement shaping on all interfaces.

Which action will accomplish?

A. Apply the input-shape-rate 5G parameter to all interfaces under the [edit class-of service] hierarchy.

B. Define a CoS input traffic control profile with the shape-rate 5G parameter and apply it to all interfaces.

C. Define a CoS output traffic control profile with the shape-rate 5G parameter and apply it to all interfaces.

D. Apply the shape-rate 5G parameter to all interfaces under the [edit class-of service] hierarchy.]

Referring to the exhibit, you have EBGP peerings with both ISP1 and ISP2. You are receiving the 172.25.12.0/24, 172.25.13.0/24, 172.25.14.0/24, and 172.25.15.0/24 routes through both neighbors. You must ensure that traffic to these prefixes are load balanced through both service providers. You have configured a load-balancing policy and have applied it to the forwarding table, but the prefixes are not being load balanced.

What is required to accomplish this task?

A. The multihop feature should be enabled between both neighbors.

B. The multipath multiple-as feature should be used between both neighbors.

C. The as-override feature should be used between both neighbors.

D. The include-mp-next-hop feature should be used between both neighbors.

B. MVRP PDUs are sent to other switches as periodic intervals.

C. MVRP can propagate dynamic VLANs created on one switch to another switch

D. MVRP is enabled by adding trunk ports under the [edit protocols mvrp] hierarchy.
